1. A method, comprising:
- receiving a plurality of data frames comprised of a plurality of bit groups in a data stream of a multi-carrier communication system, wherein up to R bit groups are identified as corrupted by analyzing corresponding tone values; and
correcting the up to R bit groups associated with one or more corrupt frames of the plurality of data frames.

20. An apparatus, comprising:
-
a receiver to receive a plurality of data frames comprised of a plurality of bit groups in a data stream of a multi-carrier communication system;
a corrupted frame detector to analyze a plurality of noise power values corresponding to tone values associated with each data frame of the plurality of data frames to identify up to R corrupt bit groups of the plurality of bit groups; and
a decoder to decode the plurality of bit groups and to correct the up to R corrupt bit groups associated with one or more corrupt frames of the plurality of data frames. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
